Description

  The present invention relates to a model for breast cancer palpation training used for training of breast cancer diagnosis by palpation.

  Conventionally, it is composed of a breast part and an attachment band that attaches the breast part to the body. The breast part forms a breast part body having the same shape and feel as the breast on a substrate provided with a simulated rib. There is a teaching material for palpation of breast disease in which a side part is extended to the side of the breast part main body, and a simulated tumor formed in the same shape and feel as the tumor is embedded in the breast part main body (see, for example, Patent Document 1).

  In such teaching materials for breast palpation, a simulated tumor having the same shape and feel as a tumor is embedded inside the breast body. Training in breast cancer diagnosis can be performed.

Japanese Utility Model Publication No. 4-55335

  However, in such a breast disease palpation teaching material, the position where the simulated tumor formed in the same shape and feel as the tumor is embedded inside the breast body is fixed, so in one breast disease palpation teaching material, Once palpation is performed, the position of the simulated tumor is known, and the next palpation training cannot be performed. Therefore, in order to perform palpation training for many types of breast cancer, there is a problem that many teaching materials for palpation of breast diseases in which simulated tumors are embedded at different positions are required.

  The present invention has been made in view of these problems, and an object of the present invention is to provide a breast cancer palpation training model capable of performing various palpation trainings using one breast cancer palpation training model.

  In this column, in order to facilitate understanding of the invention, the reference numerals used in the “Mode for Carrying Out the Invention” column are attached as necessary, which means that the scope of claims is limited by this reference numeral. is not.

The breast cancer palpation training model (1) made to solve the problem described in the above “problem to be solved by the invention” includes a breast part (10), a hole part (20), a simulated tumor part (30) , A first plug part (40) and a second plug part (50) are provided.

The breast part (10) is a resin material formed in the shape of a breast, and the hole part (20) is a plurality of holes made in the breast part (10) from the back side to the front side, and a simulated tumor The part (30) is harder than the breast part (10) and is embedded in the hole part (20) formed in a spherical shape.
Moreover, a 1st plug part (40) is inserted in the hole (20) which embedded the simulated tumor part (30) among several holes (20), and plugs up the hole (20) The second plug part (50) is for inserting the simulated tumor part (30) into the hole part (20) which is not embedded among the plurality of hole parts (20) and closing the hole part (20). Is.

  In such a breast cancer palpation training model (1), since a plurality of holes (20) are formed in the breast (10) from the back side to the front side, any one of the holes (20) is provided. When the simulated tumor part (30) is embedded in one or more, the simulated tumor part (30) embedded in the hole (20) from the outside cannot be seen.

  Moreover, since the simulated tumor part (30) is harder than the breast part (10), when the user (trainer) touches the breast part (10) with a hand or a finger, the breast part (10) is directed to the user. The simulated tumor part (30) embedded in can give a feeling like an actual tumor. In other words, breast cancer palpation training is possible.

  Moreover, since there are a plurality of holes (20), various palpation trainings can be performed with one breast cancer palpation training model (1) by changing the hole (20) in which the simulated tumor part (30) is embedded. It becomes. Furthermore, by embedding the simulated tumor part (30) in the plurality of holes (20), it is possible to perform a palpation training for a breast cancer having a plurality of tumors.

Further, by changing the hardness of the simulated tumor portion (30) and approximating it to an actual tumor or fat, it is possible to perform a palpation training on the difference between the tumor and the fat mass.
Furthermore, since the hole (20) drilled in the breast (10) is drilled from the back side toward the front side, there is no hole (20) on the front or side of the breast (10). That is, since the surface of the breast part (10) is smooth and the touch at the time of palpation is close to the breast of the human body, the degree of simulation during palpation training can be improved.
For example, if the first plug part (40) and the second plug part (50) are made of the same resin material as the breast part (10), all the hole parts (20) except the simulated tumor part (30) are blocked. Therefore, the degree of simulation when the user touches the breast (10) is improved.

  Further, when the resin material forming the breast part (10) is a urethane gel material as described in claim 2, the feel of the breast part (10) such as hardness and elasticity is close to that of the actual breast. Since the degree of breast simulation is improved, the efficiency of palpation training can be improved.

By the way, the occurrence site of breast cancer becomes each region virtually divided into four in the circumferential direction around the nipple (12) when the breast (12) is viewed from the front.
Therefore, as defined in claim 3, when the breast (10) is viewed from the front, it is virtually divided into at least four in the circumferential direction around the nipple (12). One may be arranged.

In this way, it means that the position of the simulated tumor in the breast portion (10) approximates to the actual breast cancer occurrence site, Ru can improve the efficiency of palpation training.

It is a figure which shows the schematic structure of the model for breast cancer palpation training. It is an external view of a 1st stopper part and a 2nd stopper part. It is a figure which shows the structure of the outline of the model for breast cancer palpation training which has a some breast part.

Embodiments to which the present invention is applied will be described below with reference to the drawings. The embodiment of the present invention is not limited to the following embodiment, and can take various forms as long as they belong to the technical scope of the present invention.
[First Embodiment]
FIG. 1 is a diagram showing a schematic configuration of a breast cancer palpation training model 1 to which the present invention is applied, in which FIG. 1 (a) is a front view and FIG. 1 (b) is a side view.

As shown in FIG. 1A, the breast cancer palpation training model 1 includes a breast part 10, a hole part 20, and a simulated tumor part 30.
The breast portion 10 is formed by coloring a urethane gel material, which is a resin material, into a flesh color and forming an actual breast shape. The breast portion 10 includes a protruding nipple 12 colored in a pink color darker than the flesh color on the front surface. As shown in (b), a plurality of holes 20 are formed.

  As shown in FIG. 1A, the hole 20 is virtually divided into four in the circumferential direction around the nipple 12 when the breast 10 is viewed from the front surface (nipple 12 side). At least one each (one in each region in FIG. 1A) is drilled into a cylindrical hole from the back side of the breast 10 (opposite the nipple 12) to the front side. ing.

  In addition, two or more holes 20 may be provided in each divided region, and are provided on the outer side (side of the body) of the breast as viewed from the front side where the lymph gland is likely to occur. Then, the effect of palpation training is improved (shown as the inner hole portion 21 in FIG. 1 (a)).

  The inner diameter and depth of the hole 20 may be determined depending on the size of the tumor to be simulated and the position of the tumor. That is, if the tumor to be simulated is large, the inner diameter of the hole 20 may be increased, and if the tumor is on the front side, the depth of the hole 20 may be increased.

The simulated tumor portion 30 is an elastic body such as a resin formed in a spherical shape, is made harder than the breast portion 10, and is used by being embedded in the hole portion 20, as shown in FIG.
The hardness of the simulated tumor portion 30 may be different depending on the tumor to be simulated. For example, if the breast cancer of a young patient is simulated, it is hard, and if it is a breast cancer of an old patient, it is relatively soft.

Further, the size of the simulated tumor portion 30 may be determined according to the size of the tumor to be simulated, like the hole portion 20.
(Features of breast cancer palpation training model 1)
In the breast cancer palpation training model 1 as described above, the breast portion 10 has a plurality of holes 20, and a simulated tumor portion 30 is embedded in one of the holes 20. Therefore, since the simulated tumor part 30 embedded in the hole part 20 cannot be visually observed from the outside, palpation training can be performed.

  In addition, since there are a plurality of hole portions 20, one model for breast cancer palpation training can be obtained by changing the hole portion 20 in which the simulated tumor portion 30 is embedded or by burying the simulated tumor portion 30 in the plurality of hole portions 20. 1 enables various palpation training.

  Moreover, since the material of the breast part 10 is urethane gel, the touch of the whole breast part 10 such as hardness and elasticity is close to that of a real breast, and the degree of breast simulation is improved. Therefore, the efficiency of palpation training can be improved.

  Furthermore, since the breast portion 10 is viewed from the front, it is virtually divided into four in the circumferential direction around the nipple 12, and one is arranged in each of the divided regions. Since the position approximates the actual occurrence site of breast cancer, the efficiency of palpation training can be improved.

In addition, since the hole portion 20 formed in the breast portion 10 is formed from the back side to the front side of the breast portion 10, there is no hole portion 20 on the front surface or side surface of the breast portion 10, that is, the breast portion 10. Since the surface of the skin is smooth and the touch at the time of palpation is close to the breast of the human body, the degree of simulation during palpation training can be improved.
[Second Embodiment]
Next, a second embodiment in which the hole 20 formed in the breast 10 is closed will be described. In addition, in 2nd Embodiment, since it is the same as the model 1 for breast cancer palpation training of 1st Embodiment except having made it block | close the hole 20, the same code | symbol is attached | subjected to the same part and the description is given. Is omitted.

  FIG. 2 is an external view showing a schematic shape of the first plug portion 40 and the second plug portion 50 for closing the hole portion 20, and FIG. 2A is a diagram illustrating the first plug portion 40 and the second plug portion. FIG. 2B is an external view of the first plug portion 40, and FIG. 2C is an external view of the second plug portion 50.

As shown in FIG. 2A, the first plug part 40 and the second plug part 50 are inserted into the hole part 20 of the breast part 10 from the back side so as to close the hole part 20.
The first plug portion 40 is a so-called bag made of resin such as silicon or urethane gel, which is inserted into the hole portion 20 in which the simulated tumor portion 30 is embedded among the plurality of hole portions 20 to close the hole portion 20. As shown in FIG. 2B, an insertion portion 42 and a handle portion 44 are provided.

  The insertion portion 42 is a portion that is inserted into the hole 20 and has a cylindrical shape. The outer diameter of the cylinder is slightly larger than the inner diameter of the hole 20, and the length is a value obtained by subtracting the diameter of the simulated tumor part 30 from the depth of the hole 20.

  The handle portion 44 is a portion that the user picks when the insertion portion 42 and the insertion portion 42 are inserted into or removed from the hole portion 20, and can be pulled by the user with the index finger and thumb. It has become.

  The second plug portion 50 is a so-called spear made of resin for inserting the simulated tumor portion 30 into the hole portion 20 that is not embedded among the plurality of hole portions 20 and closing the hole portion 20, as shown in FIG. As shown, a cylindrical insertion portion 52 and a handle portion 54 having an outer diameter slightly larger than the inner diameter of the hole portion 20 are provided in the same manner as the first plug portion 40.

In the breast cancer palpation training model 1 as described above, if the first plug portion 40 and the second plug portion 50 are made of the same resin material (urethane gel) as the breast portion 10, all the holes 20 except the simulated tumor portion 30 are blocked. Therefore, the degree of simulation when the user touches the breast 10 is improved.
